The Author addresses multiple purposes with the book, to "portray the unique beauty of Britain", to inspire and motivate people to get out and take pictures of the landscape, and also to give practical advice. The book is very successful in all of these, thanks to a combination of pictures and text. Peter Watson shows how one can make the best even of the inclement weather of Britain, and how that actually provides opportunities for dramatic pictures. For the combination of inspiring pictures and useful advice, I would equate it to Joe Cornish "First Light".
All this said, I am rating the book with 4 stars, instead of 5, because found quality of reproductions needs improvement: the print pattern is clearly distinguishable at normal reading and viewing distance, and in many pictures is obtrusive, bringing about artifacts (like halos around contrasty edges) and interfering with fine details. The same applies to the hard-cover edition. From a book which is about photography, I expect finer quality of reproductions. However, I must admit that the book is comparatively inexpensive. I would gladly spend twice as much for impeccable reproductions instead. I also share the grievance of another reviewer, of the double-spread picture (which I always dislike anyway) made worse by having most of the picture on one page, and the remaining slice on the opposite page.
Make no mistake, I found the book very successful in its purposes, and recommend it with no hesitation to those with an interest in taking landscape photographs. I am just very particular about the quality of reproductions in photography books.
